Hi All,

Received my kit a few weeks ago.  Thank you Matt for creating this packraft option.  A Jingda iron has arrived and been modified flat.

My educational background is organic  chemistry so I am curious about gluing joints.  A quick google search shows THF, DMF and DMSO as good solvents for TPU.  Of the readily available urethane adhesives, stabond, clifton and HH-66, I have HH-66 in stock.  HH-66 uses acetone, MEK and toluene as solvents.  Only Clifton uses THF.

First trial, HH-66 shows excellent adhesion.  Point of failure was the TPU bond to the fabric not the glue joint.
